A small number of patients overstays for a significant amount of time after they are medically ready for discharge. Though the number of patients is small, a significant proportion of bed-days is wasted in the process. The Overstay Predictor Project uses an algorithm to that uses data collected by the Critical Care and Medicine Database to predict an overstay risk. This risk is communicated to ward staff using a red sticker on charts and a direct communication to the unit manager.
